  2. An analyst was asked by a bank president to look into installingonlineterminals for all tellers. The bank has 15 tellers in the lobby and 9 tellers in the drive-in. The teller department reports to operations. The bank is organized with the followingdepartments:

    a.Operations department, which includes bookkeeping,tellers, check processing, microfilm, customer service and accounting. The department has 58 employees and 4 officers.

    b.Commercial and loan department, which handles auto loans, home improvement loans, secured loans and commercial loans for small businesses. The department has 8 employees and 3 officers.

    c.Audit department, which verifies the entire bank’s operations, audit the books and investigates cash shortages or overages.

    d.Safe deposit department, which is in charge of 6,000 safe deposit boxes housed in a vault off the lobby. 3 employees handle customer service and billing.

    e.Personnel department which performs services such as health insurance administration, recruitment, testing, training and human resources planning. The department is run by a director and1 assistant.The present system has electronic terminals that use paper tape to capture deposits, withdrawals, and other transactions. At the end of the day,thetape goes to data processing where the information is entered on tape for final processing. Ifatellerneeds an account balance, she dials bookkeeping which locks up the balance in a computer generated report. The teller then writes the balance on a slip and hands it to the customer. An online teller terminal performs the same function in a matter of seconds.
